Abstract

An absorbent pad ( 1 ) for an underweight baby has a lengthwise direction, a width direction, and a thickness direction which are perpendicular to one another, and has an absorbent body ( 2 ). The length (L 1 ) in the lengthwise direction is 180 mm or less, and the length (W 1 ) in the width direction is less than 75 mm.

What is claimed is: 
     
         1 . An absorbent pad for a low-weight infant, comprising:
 an absorbent body, wherein   the absorbent pad has a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other,   a length of the absorbent pad in the longitudinal direction is 180 mm or less, and   a length of the absorbent pad in the width direction is less than 75 mm.   
     
     
         2 . The absorbent pad for a low-weight infant according to  claim 1 , further comprising:
 a region without any elastic member is disposed outside the absorbent body in the width direction.   
     
     
         3 . The absorbent pad for a low-weight infant according to  claim 1 , wherein the absorbent pad does not have a folding line for folding the absorbent pad in the longitudinal direction. 
     
     
         4 . The absorbent pad for a low-weight infant according to  claim 1 , further comprising:
 a back sheet disposed closer to a non-skin side in the thickness direction than the absorbent body, wherein   the back sheet is made of a nonwoven fabric.   
     
     
         5 . The absorbent pad for a low-weight infant according to  claim 4 , further comprising:
 a top sheet disposed more on a skin side in the thickness direction than the absorbent body; and   a sealing portion in which at least a part of the top sheet is joined to the back sheet in the thickness direction.   
     
     
         6 . The absorbent pad for a low-weight infant according to  claim 5 , wherein the sealing portion extends along an outer edge of the absorbent pad and spaces from the outer edge at a predetermined distance. 
     
     
         7 . The absorbent pad for a low-weight infant according to  claim 6 , wherein
 the absorbent body comprises an absorbent polymer, and   the absorbent pad further comprises a portion that is a part of an entire periphery of the sealing portion and that is not peeled off even when the absorbent polymer swells.   
     
     
         8 . The absorbent pad for a low-weight infant according to  claim 1 , wherein
 the absorbent body comprises an absorbent polymer, and   a basis weight of the absorbent polymer in the absorbent body is 160 g/m2 or more.   
     
     
         9 . The absorbent pad for a low-weight infant according to  claim 1 , wherein the absorbent pad does not include an adhesive portion that fixes the absorbent pad to an underwear of a wearer. 
     
     
         10 . The absorbent pad for a low-weight infant according to  claim 1 , further comprising:
 a top sheet disposed more on a skin side in the thickness direction than the absorbent body; and   an intermediate sheet disposed between the absorbent body and the top sheet in the thickness direction.   
     
     
         11 . The absorbent pad for a low-weight infant according to  claim 10 , wherein a density of the intermediate sheet is higher than a density of the top sheet. 
     
     
         12 . The absorbent pad for a low-weight infant according to  claim 10 , wherein the intermediate sheet comprises a thermoplastic fiber. 
     
     
         13 . The absorbent pad for a low-weight infant according to  claim 1 , wherein
 the absorbent pad is capable of being attached to and detached from a skin side of an absorbent main body of a disposable diaper,   the disposable diaper has a lengthwise direction, a lateral direction, and a thickness direction that are orthogonal to each other, and   the disposable diaper comprises:
 the absorbent main body that comprises an absorbent core; 
 a pair of leakproof walls disposed on two lateral sides of the absorbent main body and are capable of rising up toward the skin side in the thickness direction; and 
 a pair of fastening tapes that protrude outward beyond two lateral end portions of the absorbent main body. 
   
     
     
         14 . The absorbent pad for a low-weight infant according to  claim 13 , wherein a length of the absorbent pad in the longitudinal direction is smaller than a length of the absorbent core in the lengthwise direction. 
     
     
         15 . The absorbent pad for a low-weight infant according to  claim 13 , wherein
 a length of the absorbent pad in the width direction is smaller than a lateral length between rising base points of the pair of leakproof walls, and   the rising base point is a point where each of the pair of leakproof walls starts to rise up toward the skin side.   
     
     
         16 . The absorbent pad for a low-weight infant according to  claim 13 , wherein a length of the absorbent pad in the width direction is larger than a lateral length between peaks of the pair of leakproof walls.
